BACKGROUND: Inflammatory bowel diseases (IBD) necessitate cost-effective biomarkers for efficient management. This study aimed to explore the potential correlations of neutrophil-to-- lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR) with IBD disease activity. Additionally, we assessed their associations with other inflammatory markers.
METHODS: We recruited 180 IBD patients with over 12 months of disease duration, categorized into two groups: Group 1 (active IBD) with 113 cases and Group 2 (inactive IBD) with 67 cases, alongside 200 group-matched healthy controls (Group 3). Hemogram, NLR, LMR, PLR, hs-CRP, ESR, fecal calprotectin (FC), and relevant parameters were recorded.
RESULTS: NLR and PLR were elevated, while LMR was decreased in active IBD patients compared to those in remission. The cutoff values for active IBD were determined as NLR > 1.98, LMR < 3.01, and PLR > 147, exhibiting sensitivity of 92%, 88%, and 91%, and specificity of 93%, 87%, and 89% respectively. Optimal cutoff values for IBD disease activity were CRP > 9.71, ESR > 24, and FC > 176. Multivariate logistic regression identified NLR, LMR, and PLR as robust parameters for discriminating IBD disease activity after adjusting for WBC, CRP, ESR, and FC markers (p < 0.05). NLR and PLR exhibited proportional increases with IBD severity, while LMR lacked such predictive capability.
CONCLUSION: NLR, PLR, and LMR emerge as simple, non-invasive, and cost-effective independent markers of IBD disease activity, complementing traditional markers like CRP and ESR.
